Abstract
A cache memory comprises a data array that stores a cashed block; a first address array that stores an address of the cached block; a second address array that stores an address of a first block to be removed from the data array when a cache miss occurs; and a control unit that transmits to a processor the first block stored in the data array as a cache hit block, when the address stored in the second address array results in a cache hit during a period before a second block which has caused the cache miss is read from a memory and written into the data array.
